Datasheet
Datasheet Summary
Powered by GS/AI

The Series 29 120A single-pole power relay is designed for heavy-duty applications in commercial and transportation vehicles, featuring a sealed housing compliant with IP67 and IP6K9K standards, 120A continuous current rating, and blow-out magnets for use with contact voltages up to 250VDC. It mounts via M3.5, M4, or M8 threads with specified torque values, and operates within a temperature range of -40°C to +85°C. The relay supports 12V, 24/28V, 36V, or 48VDC coil voltages with corresponding coil powers of approximately 7W to 10W. Dimensions include a height of 55.6mm, length of 80mm, and width of 55mm, with main terminals sized for AWG 3 wire. The relay has a mechanical life of 2 million cycles and maintains contact resistance under 175mV after life testing. Mounting structures include standard, short, long, and bottom configurations, with auxiliary contacts and suppression options available, though auxiliary contacts are not compatible with bottom mounting.
